Description

[Detailed Description of the Invention] The present invention provides a knotless support spindle that rotates on its own axis while revolving with the rotation of a spindle wheel to ensure more reliable rotation and to reduce the number of rotations. This invention relates to a net twist adjustment device.

In the process of braiding a knotless net, it is generally known that twists are applied to each strand constituting the net leg of the knotless net and to the net leg that is a collection of these strands. And these 2 kinds of Kaishiki ^Yuken++l21. Turtle

The twist applied to the net legs itself is called the top twist. The reason why the first twist is applied in this way is that if there were no first twist, the first twist that would inevitably be added during the process of assembling one set of net legs would cause the net to twist after the knitting, or the net would become twisted after the knitting. This is to offset these disadvantages since it becomes impossible to maintain a stable shape. Therefore, the first twist must be heated in the opposite direction to the first twist, but the number of twists may be equal or different depending on the type and thickness of the material used. Sometimes. In any case, in order to apply the first twist, the direction of rotation of the bobbin must be made different from the direction of rotation of the spindle.

Conventionally, the apparatus shown in FIGS. 1 and 2 has been generally used for this purpose. That is, in the figure, a is a support spindle for supporting the spindle b, and C is a twisting ring formed at a position where a notch d, through which the support spindle a is transferred, is divided into four equal parts. e is a group ring having the same shape as the twisted ring C, and f
0g is a direction change valve for transferring the supporting weight a to the next ring; 0g is a guide upper lid formed in an arc shape; and h is a pressing plate also formed in an arc shape arranged below it. i
is a guide plate that is interposed between the guide upper cover g and the pressing board, and j is two pillars installed vertically on the base. Be careful not to go too far. 1 is a spring elevating plate disposed on the column j, and m is a spring disposed on the column j between the pressing plate and the spring elevating plate l.

The pillar j passes through the pressing plate and the guide plate i and is fixed to the upper guide Mg by a screw n, and the column 0 passes through the upper guide cover g, the guide plate i, and the suppressing plate and attaches to the spring lifting plate. This is a bolt that is engaged with l. Also, p is the supporting spindle a
This is a friction disk formed around the axis q of , and this friction disk p is sandwiched between the guide upper cover g and the suppression plate.

With the above configuration, the support spindle a is the notch d of the twisting wheel C.
When the spindle a is held in the rotation direction and moves while being guided in the rotation direction, which is called revolution, the support spindle a
Since it is sandwiched between the upper guide cover g and the pressing plate, it rotates during the period of time when it passes through that part. The direction of this rotation is opposite to the direction of revolution. As a result of this rotation, a first twist is applied to the strands stored in the pobbin b.

However, in such a conventional example, over time, friction at the part of the brush that contacts the friction disk p of the pressing board, oil droplets, thread pieces, thread waste, thread powder, etc., may form between the friction disk p and the pressing board. Adhesion caused slippage, making it impossible to obtain an appropriate rotational speed, and it was extremely difficult to adjust the spring pressure at various locations, as well as the adjustment between each assembly machine. Therefore, in the braided net product, there are scattered parts where the balance between the top twist and the bottom twist is lost, resulting in kings, creases, and twisting of the mesh. The timing may be different.

There were various drawbacks such as uneven dyeing in the post-process.

In order to eliminate this drawback, an attempt was made to accurately obtain the rotational speed of the friction disk P. For example, in Patent No. 18145 and the specification, a pinion was used instead of the W friction disk of the support weight.
Also, an arc-shaped rack has been proposed in place of the pressure plate, but
Since the pinion and rack always mesh in a constant manner, it is possible to reliably apply the first twist, but it is impossible to adjust it.

Therefore, in this invention, a circular gear is formed on the shaft of the supporting weight which is rotated by a driving weight wheel, and an arc-shaped rack that meshes with this gear is disposed below the guide cover so as to be able to move up and down, thereby eliminating slippage. The present invention has been developed for the purpose of providing a knotless net pre-twisting adjustment device which is capable of uncoupling the gear and the arcuate rack as necessary.

Next, an embodiment of the knotless net lower twist adjustment device according to the present invention will be described based on FIGS. Reference numeral denotes a guide upper cover, 6 a column, 7 a base, 8 a spring, and 9 a screw, which are the same as those of the conventional example described above. 10
111ψ is a pinion of the support spindle 4, and 12 is a pinion that is loosely inserted into the support 6 below the guide cover 5. V
It is an arc-shaped rack that is bent into a letter shape. Reference numeral 13 denotes a shaft disposed from the guide upper lid 5 toward the V-shaped valley of the arcuate rack 12, and a projection 14 is fixed to the lower end of this shaft 13 in a state perpendicular to this shaft 13. . Further, at the upper end of the shaft 13, an arm rod 1G having four portions 15 is disposed. 17 is a sprocket wheel that rotates the jacquard wheel 18; 19 is a jacquard pin sent by the sprocket wheel 17; and 20 is a jacquard ball that is fitted into the jacquard bin 19 and serves as a signal source. This jacquard ball 20 is a valve 2 for braiding knots.
They are the same as those used as signal sources for opening/closing, stitching, driving the yarn handling plate, etc., and are located at predetermined locations for each purpose. Reference numeral 22 denotes a balance lever supported by a fulcrum 23. The tip of this balance lever 22 is in contact with the jacquard ball 20, and the other end is engaged with a protrusion 25 of a connecting rod 24. A fan plate 26 is rotatably supported by a fulcrum 27, and is connected to the connecting rod 24. 28 is a plurality of bottles protruding from the fan plate 26, and 29 is a hook that engages with the bins 28. This hook 29 is further connected to one end of an L-shaped lever 31 via a piano wire 30.

This lever 31 has a bending portion 32 rotatably attached thereto, and the other end of the lever 31 is connected to another piano wire 33.
are connected. This piano wire 33 passes through the recess 15 of the arm rod 16 described above.

It passes through the frame 34 and is further pulled by a spring 35. Reference numerals 36 and 36' designate actuators fixed to a portion of the piano wire 33, one each on the frame 34 side and the opposite side of the arm rod 16.

When the twisting ring l is rotated, the supporting spindle 4 also revolves, and is transferred to the assembled ring 2 or another twisting ring l as necessary by the valve 21, but the process of revolving on the twisting ring l In this case, the gear lO formed on the shaft 11 of the support weight 4 meshes with the arcuate rack 12, so it rotates in the direction opposite to the rotation of the twisting ring l, and in this process, so-called pre-twisting is applied. . Therefore, in order to apply the first twist in this manner, it is necessary that the gear lO and the arcuate rack 12 mesh with each other. By the way, in order to temporarily not apply the first twist at a certain point, that is, to disengage the gear 10 and the arcuate rack 12, do the following. That is, the jacquard 18 is moved as the sprocket wheel 17 rotates. When the jacquard ball 20 contacts the tip of the balance lever 22, the other end is pushed up with the fulcrum 23 as a boundary, and the fan plate 26 is rotated upward by the connecting rod 24. Then, this causes each piano wire 30 to branch the signal, that is, the signal from the jacquard ball 20. The piano wire 30 then pulls up one end of the L-shaped lever 31 and moves the piano wire 33 connected to the other end to the right in the drawing.

Then, the arm rod 16 is pulled by the single actuator 36.

In other words, it rotates 90 degrees. When the arm rod 16 rotates 90 degrees in this manner, the shaft 13 also rotates 90 degrees, and therefore the protrusion 14 also rotates 90 degrees. Since this protrusion 14 exists in the V-shaped valley of the arcuate rack 12, when it is rotated 90 degrees in this way, the arcuate rack 12 is pushed down against the spring 8 pushing up from below. In this way, the arcuate rack 12 is disengaged from the gear 10. Moreover, this happened almost instantaneously when the jacquard ball 20 on the sprocket wheel 17 pressed the balance lever 22.
At the next moment, there is no jacquard ball 20 again, so the sprocket wheel 17 side of the balance lever 22 rises, which means that the piano wire 33 is pulled by the thread ring 35, and there is no longer anything to support the arm rod 16. At the same time, the arcuate rack 12 is pressed from below by the spring 8 and rotates the protrusion 14 of the shaft 13 by 90 degrees when it hits the actuator 36' on the opposite side.
The protrusion 14 of No. 3 rotates 90 degrees in the opposite direction as if being repelled, and the arcuate rack 12 rises, thereby meshing with the gear IO again. These things are the sprocket wheel 17
The rotation of the jacquard ball 20 causes the jacquard ball 20 to come into contact with the balance lever 22 or not, depending on the timing. However, it is also possible to provide a continuous tooth profile as shown in FIG.

As mentioned above, according to the knotless net pre-twisting adjustment device of the present invention, the bobbin is caused to rotate by meshing with the gear and the arcuate rack, so there is no slippage, and the number of rotations due to the revolution of the support spindle is reduced. Since the net legs can be adjusted appropriately, the balance between the top twist and the bottom twist of the net legs can be easily maintained, and the net can be braided without twisting or twisting. It has many effects such as being able to easily maintain the same coloring and preventing uneven dyeing in subsequent steps.
